SPECIFICATION forming part of Letters Patent No. 378,849, dated February 28. 1888.

Application filed November 6, 1886. Serial No. 218,187. (No model.) A

To @ZZ whom it may concern:

Be it known that we, ELMER L. POTTER and GEORGE B. UPHAM, citizens of the United States, and residents of Columbus, Franklin county, State of Ohio, have invented new and useful Improvements in Envelopes, of which the following is a full and exact description, reference being had to the accompanying drawings, making part of this specification.

This invention relates to improvements in envelopes, and more especially to that class of envelopes in which articles of value are deposited for safekeeping.

In the drawings, Figure 1 is a view of the blank. Fig. 2 is a view of the envelope folded to receive an article for deposit. Fig. 3 is a view of the envelope sealed, showing the printed matter upon both the flap of the envelope and the coupon. Figs. 4. and 5 are detail views of the coupon. Y

This envelope is intended for the use of liol tels, bathing-houses at summer resorts, parcel-rooms at depots, and like places,where valuables are recei-ved and kept until called for.

The letter A designates the body of the envelope; B, a flap corresponding in size to the said body and provided with an extension,.O; D D, iiaps on opposite sides of the said body, provided with sealing material in their under face; E, a flap corresponding in size to the said body and provided with sealing material upon the three outer edges; F, a coupon attached to said ap E and perforated along the line of attachment; F', a folding extension of said coupon F, provided on its under face with sealing material tosecure it to the said coupon.

To construct these envelopes from the blank, as shown in Fig. 1.4 of the drawings, the parts are folded as follows: the fiap B is iirst folded upon the body A. The flaps D D are then folded down on the flap B and secured to it by the sealing material on their lower or inverting faces. In this position the extension C of the flap B extends above the iiaps D D, as shown. This isnext turned down loosely upon the flaps D D and B. The extension F When the envelope is now used, the depositor places his valuables in the pocket formed by the body A and liaps B and D D, and folds the fiap E upon the whole after wetting the sealing material. When the said flap is thus folded, the sealing material adheres to the sides of the extension C and to the flaps B and D D, thus completely sealing the envelope.

When the envelope is sealed, as above described, the depositor fills out the blanks printed upon the back of the envelope and signs his signature upon it, upon the back of that portion where the sealing material is placed. The clerk receiving the package then signs the coupon, as designated, and delivers the same to the depositoras a receipt. The coupon and the back of the envelope are printed to correspond, substantially as shown. The purpose in thus placing the signature of the depositor upon the part provided with sealing material is to prevent tampering with the seal undetected. The usual method, and the one it is hereby sought to prev-ent, for accomplishing this end is by application of water or steam to the back of the sealed portion to loosen the seal by softening the sealing material. ture is Written upon that portion ,without the ink running when such application is made.

When the flap E is folded upon the pocket of the envelope, it adheres to the eXtensionU. This prevents the introduction of any instrument into the pocket of the envelope without destroying the envelope at that point.

When the depositor now calls for his package, he signs the coupon, as designated, and gives it to the clerk'in charge as a receipt for the package. If, by accident or otherwise, he cannot personally call for his deposit, he can, by signing his name to the coupon and send- By this u This is impossible when the signal ing the saine to the place of deposit, have the paper folded upon itself 'and sealed, substanro package delivered to whoever he sends. Actially as set forth.

cident or fraud is `guarded against, as the sig- In testimony whereof We have hereunto set natures upon the coupon and the envelope our hands this 23d day of October, A. D. 1886. 5 must agree. ELMER L. POTTER.

Vhat we claim is- GEORGE B. UPHAM. An envelope such as described, provided Witnesses: with a coupon attached to one of the flaps, C. XV. BIURDOCK7 said coupon consisting in a double length of L. D. HAGERTY.
